IMPROVEMENT IN DITCHING AND GRADING MACHINES.

Specification forming part of Letters Batent No. 109,091, dated November8, 1570.

To all whom it may concern:

Be it known that I, HIRAM A. WINTER, of Windsor, in the county of Shelbyand State of Illinois, have invented a new and useful Iniprovement inDitchi ng and Grading Machines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecication, in which- Figure I is a side view of my improved machine.Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved machine foropening ditches, and for grading roads and other places,which shall besimple in construction, inexpensive in manufacture, and effective inoperation; and it consists in the construction and arrangement of thevarious parts of the machine, as hereinafter more fully described.

A are the side bars of the frame of the machine, the forward ends ofwhich meet at an angle, and are securely attached to each other. Thebars or beams A are connected and held in their proper relativepositions by one or more cross-bars, a.

B is the share, which is attached to the outer side of the forward partof one of the side bars or beams A. The extreme forward end of the otherbar or beam A should be faced with a metal plate, C, which may be acontinuation of the share B or a separate piece, as may be desired orconvenient.

D is the nose or point, which should be made separate, and should bebolted securely to the angle of the bars A. One edge or flange of thenose or point D should slightly overlap the forward end of the landsidebar or beam A, and its other side or flange should overlap the forwardend of the other bar or beam, and should be grooved and jointed to theshare. This construction allows the nose or point D to be convenientlydetached when worn and replaced by a new one.

E is a caster-wheel, the standard F of which passes up between theforward parts of the bars A, passes through a guide-bar, G, attached tothe upper edges of the said bars A, and its upper end passes through andis adjustably secured to the lever H by a nut or nuts screwed upon thesaid standard F. The forward end of the lever H is connected by aswivel-connection, I, to the bar J, attached to the forward ends of thebars A. The lever H passes back to the rear part of the machine, and isconnected with a guide-bar, K, attached to the rear cross-bar, c', ofthe frame A. The guide-bar K has several holes formed through it toreceive a pin to hold the lever H securely in any position into which itmay be adjusted. By this construction the forward end of the machine maybe raised from the ground for convenience in turning. In recesses in thelower edge of the landside-barA are pivoted revolving cutters L, whichenter the ground and resist the side pressure upon the other bar or sideof the machine, holding the machine to its work and causing it to movestraight forward.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The share B, nose D, and plate O, combined andattached to a supporting-frame, A A, as and for the purpose described.

2. The device B O D, combined on aframe, A A, with the revolving cuttersL L, as and for the purpose described.
